Well it's none of her business hun so don't let that bother you in the slightest! I don't know much about tongue ties, I actually thought they all got cut when they were newborn which obviously isn't the case - but would she even know? You could just not mention it to her if you think you'll just get criticism.
Would you be able to express before you go to bed as a way of getting a bit more expressed milk? I know you said Lily won't feed if she's woken up and tired so maybe that's a way of getting a bit extra out, then you should be nice and full again by the time she wakes up on a morning.
Fingers crossed for you that the thrush goes quickly, that's the last thing you both need!
